' part of this specification.

My invention relates .to a wedge for service in holding tools, suoli as axes, hatohets and hammers provided with eyes, to their handles, the wedge being so produced as to provide for the retention thereof in the handle in Which it is introduced without the employment of any agency other than that contained in the wedge itself.

Figure I is in part an elevationandin part a section of an ax applied to its handle or helve and my wedge in position for hold` ing the ax upon the handle. Eig. His an end. elevation of the part shown in Figi. Fig. IH is a longitudinal section taken-on line Ill-lll, Fig/IV. Fig. IV is a longi tudilnal section taken on line lV-IV, Fig. I. Fig. V is a perspective view of my wedge.

In the accompanying drawings: Adesivnates an ax provided with the usual eye d3 and C is the wooden handle seated in the eye of the ax.

1 designates my wedge which is provided at its inner end with a knifev edge 2. At one side ,of the wedge and extendlng from its butt to a point between the butt and the knife edge 'of the wedge is a groove 3 that leads to an opening 4 extending through the wedge, thereby providing a knife member 5 which terminates at the top of the Opening 4 in a. cutting-'edge 6.V At the side of the wedgev opposite to that at which the groove 3`is located is a groove 7 that extends inwardly from the knife edge 2 of the 'wedge and terminates at the bottom of the opening 4e and in a position oE-sgt laterally from the cutting edge 6 at the top of s id opening. The termlnation of the groove,7 is preferably in alinement with the knife edge 2. of

,the wedge to provide a cuttin l edge at the vide a notch in the knife` edge of the wedge, as seen in Figs'. I and V.

When thev wedge is .driven -finto av tool handle-'for the'purpose of seati ittherein in the .positions lshown the rawings, a splinter C is cnt "from the wood ofthe tool handle which 'is spl-itby-drivingthe wedgev into place, the f rodi-lotion of this splinter, being due to t e woodfrom which. thev splinter isimade riding'in gthe groove '7 one side 'of the wedge untily it reaches the opening 4 in the wedgeand then passes through said openin into the groove 3 at the opposite side o the wedge. At this time the wedge is out into the splinter C which enters into and passes upwardly in the groove 3, thereby 'causing said splinter to serve as a retaining member for the wedge.

'The groove 3 is inclined `relative to the Width anglevto the point at which its inner end is joined tothe tool.

I preferably `provide two sets of .the

grooves hereinbefore described in the wedge for additional increased support in the holding of the wedge by two splinters instead of a single splinter produced from thetool handle and in so doing the second groove designated 3 corresponding to the first groove 3 is located at the reverse side of the wedge rela'tive to that at. which the groove 3 is located and the second groove designated 7 is located at the reverse side of the wedge relative to the side at which the groove 3 and the-groove 7 is located. The opening 4: provides communication between the grooves 3 and 7 and a knife member 5 similar to the knife member 5 and having a cutting edge 6 at its inner end extends to the opening 4. It will be seen that by locating the grooves 3l 'and 7 reversely relative to the grooves 3 and 7, I provide for the production of retaining splinters which extend to opposite sides of the wedge and which have-oppositely directed influences for the retention of the wedge in the tool handle.

4l. A wedge of the character described having 'an opening therein intermediate of opening7 and a groove extending from the the inner end of the wedge to said opening,

inner end of the wedge to said opening7 substantially as set forth.

2. A Wedge of the character described having an opening therein intermediate of its ends, a groove tapered at and leading from said opening toward Athe outerend of the wedge and inclined relative to the width of the Wedge, and a groove extending from substantiall r as set forth.

3. A We ge 'of the character described, having two openings therein intermediate of its ends, grooves tapered at and leading from said openings toward the outer end of the wedge, one ofv said grooves being located l at one side of the wedgeand the other groove being located at the other side ot the Wedge, and lower grooves extending from the inner ends of the wedge at the sides thereof to said opening,7 substantially as set forth.

4. A wedge of the character described, having two openings therein intermediate of its ends, upper grooves leading from said opening toward the outer end of the Wedge, one of said grooves being located at one side of the Wedge and the other groove being located at the other side of the wedge, and lower grooves extending from the inner ends of the wedge at the sides thereof to said `opening; said wedge being provided with cutting edges' at the tops of said openings, substantially as set forth.

5. A wedge of having two openings therein intermediate of its ends, upper grooves leading from said openings toward the outer end of the wedge; one of said grooves being located at one side of the wedge and the other groove being located at the other side of the wedge, and lower grooves extending from the inner ends of the wedge at the sides thereof to said opening; said wedge being provided with cutting edges at the tops of said openings, and said grooves being inclined relative to the Width of the Wedge, substantially as set forth.

6. A wedge of the Vcharacter described,

having an opening intermediate of its ends;

a groove extending from the inner end of th'e Wedge to said Openingat one side of the Wedge, and a groove extending from said opening toward the outer end of the Wedge and located at the-side of the Wedge opposite to that at which the first named groove is located, substantially as set forth.
